Size Guide

How to find your ideal size

  1. Step 1 : Measure the circumference of your finger above the knuckle (You can use a thread or a piece of paper, marking it with a marker as in the video)
  2. Step 2 : Find the circumference measurement in millimeters in the table and look up the corresponding size in the Spain, European (EU), United States (US), or United Kingdom (UK)/Australia (AU) sizing systems.
  3. Another alternative : measure the inner diameter of a ring that fits you well.

Example :

If you measure a circumference of 56 mm, your size would be:

  • Spain : Size 16
  • EU : Size 56
  • US : Size 7 ½
  • UK/AU : Size O

Tips to ensure the perfect fit :

  • If you are between two sizes, choose the larger size, especially if the ring is wide.
  • If your hand size varies slightly between your two hands, remember that your dominant hand tends to be slightly larger.
  • It is always better to measure your finger than a ring as rings may have changed shape over time.
